Glad to see you got your Cub back up to power. The only thing I have to add regards the smoke you are seeing. From what I could see in your video, the smoke only seems to occur on cranking and when the engine first takes up a load (climbing a hill, engaging the mower, etc.), and then clears up. From what I understand, that's perfectly normal - except that it is generally a bit darker, more towards black (ill have to say the white smoke had me concerned at first, but it seemed to clear up in no time) - and all internal combustion engines do this. Maybe the white color has something to do with the additive you're using?

Anyway, it's great that you are up and running.

Thanks Jim The smoking I've seen since it has been back up and running properly is variable. Sometimes it smokes a little and seemingly under the exact same conditions, smokes A LOT. I've run the fuel down, and cleaned out the bowl since the additive. Guessing it's just burning oil (it has a slight blue haze to it) and showing when I cant control one variable: heat. Either way, I couldnt be happier! Just hoping to find my grinding gremlin now

If you added some SeaFoam to the gas and to the crankcase, this is normal and nothing to worry about as the SeaFoam is doing it's thing. Wait for a bit and see what happens, the smoke may simply be carbon burning off.
